Mexico investigates possible female 'bus driver hunter'

CIUDAD JUAREZ, Mexico - Mexican prosecutors said Monday they are investigating claims that a woman who killed two bus drivers last week in this northern border city was seeking revenge for alleged sexual abuse of female passengers.

The claims made in an email from the self-styled "bus driver hunter" echoed deeply in Ciudad Juarez, which has a grim history of violence against women aboard buses.

A woman wearing a blond wig - or dyed hair - boarded one of the school bus-style vehicles that serve as transport in the city on Wednesday. She approached the driver, took out a pistol and shot him in the head. The next day, apparently the same woman did exactly the same thing to another driver on the same route.

Over the weekend, media outlets began receiving emails from the address "Diana the hunter of bus drivers."

"I myself and other women have suffered in silence but we can't stay quiet anymore," the email said. "We were victims of sexual violence by the drivers on the night shift on the routes to the maquilas," a reference to the border assembly plants that employ many residents in Ciudad Juarez. "I am the instrument of vengeance for several women."

Authorities have not verified the authenticity of the email, or of a Facebook page set up under a similar name Aug. 31.
